Abstract (en)
[origin: WO9414174A1] A transformer secondary winding comprises a laminated structure which includes first and second outer sheets (11, 13) fabricated from an insulator material, sandwiched between the outer sheets is a thin flexible sheet (12) of a magnetizable material. The first and second outer sheets each have a parallel conductive line pattern on a surface thereof. Selected ends of the lines on the first sheet are connected to the selected ends of the lines on the second sheet in such a manner as to provide a coiled pattern between the sheets, which coiled pattern encircles the central magnetizable sheet. The above laminated configuration can be flexed or rolled into a circular configuration to form a transformer secondary winding. The circular secondary windings are concentrically positioned about a first primary cylinder (70) fabricated from an insulator sheet having parallel conductor elements (125, 126, 127 and 129) arranged on a surface thereof. A second outer primary cylinder (79) surrounds the secondary windings at the outer periphery and is fabricated from an insulator sheet having a conductive line pattern (100, 101, 102) on a surface. The conductive lines of the first and second cylinders are connected to form a primary winding about the secondary windings to provide many different transformer configurations.
